Title: Loudspeaker communication set
Inventor: TAKEYAMA HIROAKI
IPC: H04M1/60
Filed: 1988-03-28
Abstract: PURPOSE:To send a transmission voice in the state not causing reception block by picking up a voice from a speaker by means of a couple of microphones, applying delay and level adjustment to cancel the voice component from the speaker inputted to both the microphones by a differential amplifier circuit. CONSTITUTION:A couple of microphones M1, M2 are arranged on the surface of a housing 1 so as to be exposed on the same face as the speaker S and the distance from the center of the speaker S and the center of the microphones M1, M2 is set respectively to l1, l2. The delay circuit 22 is set to obtain a delay time corresponding to the time difference when the voice generated from the speaker S reaches the microphones M1, M2. The signal corresponding to the voice from the speaker S is cancelled in the differential amplifier circuit 24 receiving both the output of the delay circuit 22 and the output of the level adjustment amplifier circuit 23. Thus, the output level Lt of a transmission level detection circuit 27 reaching larger than the output level Lr of a reception level detection circuit 14a is avoided and the occurrence of the reception blocking is prevented.

Title: Driving apparatus
Inventor: CHIBA AKIRA
IPC: H02K7/09
Filed: 1995-03-30
Abstract: PURPOSE: To enable adjustment of a tension of a long-length material by introducing a structure that the position of rotor in the radius direction can be controlled by feeding an electrical power to a coil for generating a force in the radius direction depending on a tension of the long-length material detected by a rotating position detector. CONSTITUTION: At the center of a driving apparatus 1, a stator 2 is provided as an armature and both torque generating coil and radius direction force generating coil are wound thereto, and moreover a rotor 3 of a permanent magnet magnetized in the number of poles equal to the number of poles for torque generation coil is also arranged to surround the stator 2. Moreover, at the external side of the rotor 3, a cylindrical rotor 4 is arranged in integration with the permanent magnet and is rotably supported by inserting a center shaft 7 into the center aperture of the disk type base 5 provided at the lower end via a bearing 6. When the power is supplied to the radius direction force generating coil loaded to the stator 2, a radius direction force is actively generated, enabling the rotor to be displaced in the radius direction.  As a result, the tension is controlled to the minimum value for preventing looseness of the long-length material wound around the rotor.

Title: Fluorescent printer
Inventor: NAKAMURA SHIGETAKA
IPC: B41J2/44
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To obtain a required print density even after a print head is left without generating light for a long time by providing a pre-emission mechanism which makes a phosphor element emit light before the phosphor element corresponding to an image is driven. SOLUTION: In a fluorescent printer which has an exposure print head 60 with a phosphor element FD and exposes a photographic paper 3 by driving the phosphor element FD in accordance with given image data, a quantity of exposure light tends to decrease because of a 'leave characteristic' of the phosphor element FD if the print head 60 is left without generating light for a long time, as compared with before the print head 60 is left. A preemission mechanism is attached to the fluorescent printer, which lets the phosphor element FD emit light before the element is driven normally on the basis of the image data. The pre-emission mechanism detects a time while the print head 60 is left, i.e., while the print head 60 is stopped driving, and works to let the phosphor element emit light preparatorily when the time exceeds a set value.

Abstract: PURPOSE:To manufacture a high-chromium ferritic steel excellent in creep strength by subjecting a steel containing specific amounts of C, Si, Nn, Cr, Ni, Mo, V, Nb, Al, and N to specific hot working and then to specific normalizing. CONSTITUTION:A steel having a composition containing, by weight, 0.05-0.15% C, <=0.5% Si, <=1.5% Mn, 8.0-12.0% Cr, <=1.0% Ni, 0.81.3% Mo, 0.01-0.30% V, 0.01-0.30% Nb, <=0.20% Al, and 0.005-0.10% N is subjected to hot working, normalizing, and tempering. In the manufacturing method for the above high- chromium ferritic steel, the precipitation of alloying elements is inhibited by regulating the final working temp. of hot working temp. to a temp. in a region as high as >900 deg.C. Further, normalizing is carried out at a temp. in the region as low as 870-1000 deg.C. By this method, the creep strength of the high-chromium ferritic steel can be maintained at high value without performing normalizing treatment in the high-temp. region, by which manufacturing costs can be reduced.
